STOCK-BOX. A I

To all whom it may concern;

Be it known that I, WILLIAM PL.

MOND, a citizen of the United States, residing at Boston, in the countyof Suffolk and State of Massachusetts, have invented certainImprovements in Stock-Boxes, of which the following description, inconnection with the accompanying drawing, is a specification.

This invention relates to boxes and in particular to boxes used inmanufacturing establishments for transporting manufactured articles fromone portion of the plant to another, said boxes being practically trayshaving no tops but permanently open for the deposit of articles thereinand so as to be easily emptied. It has been found that boxes used forthis purpose deteriorate very rapidly in use owing to the severetreatment which they experience, especially when metal articles aredropped therein, or if the box is emptied by tilting it. It is theobjoct of my invention to provide a stock box which will stand an almostunlimited amount of abuse and which at the same time is. not expensiveto manufacture.

A feature of my invention is a box comprising pairs of mutuallyoverlapping, opposed side and end members, whereby the collapsing of theside and end members toward each other is prevented, and bolts joiningthe opposed members of each pair, the top being open and the bottombeing easily removable when worn or broken.

The drawing is a View in perspective, with portions broken away, of abox constituting a preferred form of the invention. V The box comprisestwo side members 10 and two end members 11. The end members are rabbetedat 12 to receive the side pieces 10. It is thus impossible for the sideor end members to collapse toward each other. The end and side piecesare channeled at 13 and 14 respectively. Lock rods 15 and 16 are mountedin these channels and extend through the sides and ends of the box.

Angle irons 17 are mounted upon the cor- Specification of LettersPatent. H 23, Application filed September 18, 1915. Serial No; 51,444.

for the corners. The; .rods 1.'O l' etie .bOltSprlfi, 16 are aboutmidway of the height of the box and their ends pass through the angleirons substantially at the mid-length thereof. Therefore when the box isset up it has strong corners although there is but one rod or tie boltextending through each wing of each angle iron. The tension of the tierods is applied to the angle irons only at the mid-length of the latter,but that tension is distributed by the upper and lower portions of theangle irons to the upper and lower corner portions of the box tostrengthen those portions without employment of other fastening means.The side members 10 are channeled at 19 for the reception of the ends ofthe bottom boards 20. These bottom boards, when worn or broken, may beeasily replaced by new sections after simply removing two of the angleirons and setting one of the side members 10 aside without disassemblingthe ends 11 from the other side member, and without removing any of thetie rods.

It will be clear that this box is fastened together by four bolts onlyand that it may be readily knocked down and packed in small compass. Itwill be clear that the four steel bolts 15, 16 and the angle irons 17will support the box without injury un der stresses which would wreck adevice fastened with ordinary nails and screws. It will be observed alsothat the bottom of the box exerts a much stronger bracing effect uponthe four vertical members than would be true of a bottom which wasnailed or screwed to the vertical members since all the distortingstress exerted upon the bottom by the vertical members of the box is acrushing stress without any tendency to split, and the bearing surfacecommunicating stress between the vertical members and the bottom is amaximum. The same is true of the reaction at the corners of the verticalmembers, where the side and end members mutually overlap. Any attempt todistort the box can result only in a compressive stress upon thevertical members at the corners. There is no tendency whatever to tearthe vertical members since all the tensile stresses in the box are takenby the four steel rods. It is contemplated that the vertical and bottommembers of the box will be made of wood and it is well known that thismaterial exhibits greater resistance to a bottom for the box removablymounted in compression than to tension. said grooves, a single metalangle plate e111- Having described my invention, what I bracing eachcorner, anda single adjustable claim as new and desire to secure byUnited tie bolt extending along the inner face of 5 States LettersPatent is each wall member and passing through an 15 A Wooden boxcomprising pairs of opangle plate at each corner substantially midposedsingle Wall members, one pair having Way of its length.
